Simple, Novel Process for Isolating Cannabinoids from Complex Crude Hemp Extracts to Replace Winterisation and Other Energy Intensive Processes

The current industrial process to purify CBD from C. sativa extracts is long and intensive, requiring several steps such as winterification for 48 hours at -45 C and high-temperature, high vacuum distillation. These processes are capital-intensive and generate large amounts of toxic solvent waste. In contrast, the methodology proposed herein could change the way CBD is obtained, doing so in a single step that is fast and reusable. Furthermore, the new process is simple and easily implemented and does not require any intensive operator training.
